a wireless frame including a frequency domain and a time domain is divided into at least the first and second zones in the frequency domain or the time domain.

2. The wireless communication system according to claim 1, wherein the wireless resource further divided in the time domain or the frequency domain is allocated within the first or second zone to the processing unit, if the wireless frame is divided into the first and second zones in the time domain

3. The wireless communication system according to claim 1, wherein the wireless resource further divided in the time domain and the frequency domain is allocated within the first or second zone to the processing unit, if the wireless frame is divided into the first and second zones in the time domain.

4. The wireless communication system according to claim 1, wherein the wireless resource further divided in the time domain or the frequency domain is allocated within the first or second zone to the processing unit, if the wireless frame is divided into the first and second zones in the frequency domain.

5. The wireless communication system according to claim 1, wherein the wireless resource further divided in the time domain and the frequency domain is allocated within the first or second zone to the processing unit, if the wireless frame is divided into the first and second zones in the frequency domain.

6. The wireless communication system according to claim 1, wherein the first terminal device includes a distance measurement unit which measures the distance between the first and second terminal devices, an allocating unit which allocates the wireless resource within the first or second zone in accordance with the measured distance, and a transmitting unit which transmits the allocated wireless resource to the second terminal device.
